TAKE-UP MECHANISM FOR LOOMS.

No. ss1,9o4.

Original application filed June 13, 1905, Serial No. 264,992.

Serial No.

T0. all whom it may concern:

' Beit known that I, GEORGE S. Cox, a citizen of the United States,residing at Fitzwatertown county of. Montgomery, and State ofPennsylvania, have invented a new and useful Improvement in Take-UpMechanism for Looms, of which the following is a full, clear, and exactdescription, reference being had to theaccompanying drawings, which forma part of this specification.

This application is a division of an application filed by me June 13th,1905, Serial No. 264,992. In that application is described a loomadapted to the manufacture of hair cloth and having various novelfeatures, and the improved take-up mechanism forming part of such loomis the subject matter of this application. It will be understood,however, that this improved take-up mechanism may be found available foruse in other types of looms than the one particularly set forth in saidapplication.

The special object of the invention is to have the take-up mechanism actuniformly and with certainty.

Figure 1 is a side elevation of a portion of the loom frame and thetake-up mechanism; and Fig. 2 is a front elevation of the same.

The other parts of the loom are not shown, as their specificconstruction is of no importance.

a is the frame of the loom having suitable bearings for the spindles ofthe guide roller 0, cloth roller (1, and take-up rollers d and (Z andfor the shaft of the ratchet wheel 0.

g is a spur gear on the shaft of ratchet wheel 6.

h is a spur gear on the spindle of the take up roller d.

i, 9', 75, Z are the gears connecting gears g and h.

d is another gear on the shaft of roller d, engaging a gear (Z on theshaft of roller (Z (Z is a pulley on the shaft of roller d.

d is a pulley on the shaft of the cloth roller d, and d is a beltconnecting pulleys (Z and d. The ratchet wheel, which is operated by thelay in the usual manner, operates the take up rollers d and (Z throughthe chain of gearing above set out, and the roller (1 operates the clothroller (1 by means of the belt and pulley connection described. Thecloth from the loom passes down to, under, and partially around take-uproller Specification of Letters Patent.

Divided and this application filed December 27, 1905. 293,444.

(Z, thence up to, over, and partially around take up roller (1 andthence down to the cloth roller. The take up rollers (Z and-(Z areroughened.

Takeup mechanism for hair cloth looms, as usually constructed, consistof a roughened roller, on which is superimposed a pressure bar.Sometimes a roller, driven positively or frictionally, is substitutedfor the pressure bar. The cloth passes between the roughened roller andthe pressure bar, the clothbeing carried along by reason of the pressurebar holding the cloth in contact with the roughened surface of thetake-up roller as the latter turns. In course of time, this constantfrictional contact of the pressure bar and take-up roller wears away theroughened surface of the roller, so that the feeding action of the samebecomes uncertain. This results in an occasional and sometimes frequentfailure of the cloth to feed forward after each beat of the lay, causingthe cloth to contain more picks to the inch than the take-up wheelindicates. Thus two evils are produced, one of which is an irregularityin the closeness of the picks, while the other of which is that themanufacturer suffers loss by reason of the cloth containing more picksto the inch than enter into his calculations.

The improved take-up mechanism above described entirely obviates thesedefects. The two take-up rollers arranged as shown and spaced apart actas an effective substitute for the single take-up roller and pressurebar commonly used. As these rollers are not in contact with each other,and do not feed the cloth forwardly by pressing the cloth between them,there are no conditions giving rise to any wearing away of the roughenedsurface of either of the take-up rollers. Consequently, these take-uprollers are extremely durable and will last indefinitely without anydiminution in their efficiency.

Having now fully described my invention, what I claim and desire toprotect by Letters Patent is:

1. In a take-up mechanism for looms, in combination, a cloth roller,take-up rollers, having a roughened surface, to and about which thecloth is adapted to pass on its way to the cloth roller, said take-uprollers being spaced apart a distance suflicient to permit a givenlength of cloth on its way from one take-up roller to the other to beout of contact with either roller, and means positively actuating thetake up rollers.

2. In a take-u mechanism for looms, in combination, a c oth roller,take-up rollers, having a roughened surface, to and about which thecloth is adapted to pass on its way to the cloth roller, each rollerbeing spaced from the neXt roller of the series a distance sufficient topermit a given length of cloth between such rollers to be out of contactwith either roller, means positively actuating the take-up rollers, anddriving connections from the take-up rollers to the cloth roller.

3. In a take-up mechanism for looms, in combination, a take-up rollerdown to and under which the cloth is initially fed, a second take-uproller above the first take-up roller up to and over which the cloth isfed from the first take-up roller, said take-up rollers being spacedapart a distance sufficient to permit a given length of cloth on its wayfrom one roller to the other to beout of contact with either roller, acloth 7 roller beneath the first take up roller down to which the goodsare fed from the second take up roller, and means to positively driveall the rollers.

4. In a take-up mechanism for looms, in combination, the cloth-roller, aplurality of take-up rollers, one, nearer the cloth-roller,

to which the cloth'is fed from the guideroller, and one, nearer theguide-roller, from which the cloth is fed to the cloth roller, and meansto positively drive the take-up rollers, each roller being spaced apartfrom the next roller of the series a distance sufiicient to permit alength of cloth at any given time feeding between them to be out ofcontact with either roller.

In testimony of which invention, I have hereunto set my hand, atPhiladelphia, on this 21st day of December, 1905.
